Well over a century on since the first wireless radio transmission from the Isle of Wight, voices from the ether continue to inform, educate and entertain us, even sometimes to save our lives. Alan logs on to connect with three of them. In Kodiak, Alaska, Terry's public radio fisheries reports are at the cutting edge of climate change. In Sydney, Ben is embracing the podcast revolution. And in St Helena, Sharon hosts a local community radio show on this, one of the most isolated islands on earth.
